Abstract: Methods for dewatering a fiber suspension in a twin-wire press, having a lower wire and an upper wire, and a first and a second dewatering table, which supports the wires such that a dewatering space is defined by the wires, are disclosed. The wires transport the fiber suspension under compression of the wires by the dewatering tables, such that the fiber suspension is dewatered and forms a fiber web between the wires. A separate pressing force is applied against one of the wires, such that this wire presses the formed fiber web via the second wire against one of the dewatering tables and further dewaters the fiber web. The separate pressing force is adjusted such that a desired dryness of the fiber web leaving the dewatering tables is achieved. A twin-wire press is also disclosed.

Title: Filterkasett
Inventor: BO DOLK
IPC: B01D46/30
Filed: 2015-12-15
Abstract: Uppfinningen är filterkassett avsedd som orienteras i ett bruksläge. Filterkassetten har minst två filterceller som i sitt inre innesluter en filtersubstans. I bruksläge har filterkassetten en större höjd än bredd, medan i bruksläge har filtercellerna en större bredd än höjd och filtercellerna avgränsas uppåt och nedåt av separationsstag (1) som sträcker sig horisontellt. Höjden på stapeln av filtersubstans hålls därigenom så låg som möjligt, så risken att filtersubstansen komprimeras hålls låg.Eftersom filterkassetten i bruksläge har en större höjd än bredd och är försedd med separationsstag som sträcker sig från filterkassettens ena sida till dess motstående sida, uppnås en optimal vridstyvhet. Filterkassetten far på så sätt en optimal motståndskraft mot yttre mekanisk inverkan. Hade filterkassetten varit mer eftergivlig hade den vid belastning ändrat form i högre utsträckning och detta lett till att filtersubstansen kunna sjunka ihop, men denna effekt minimeras nu.

Abstract: The method is for encapsulating radioactive waste (1) in a capsule (4) for final storage, where the encapsulation occurs in a treatment station incorporating a water-filled basin (3) and at least one space (14) with radiation-screening walls. In the water in the basin the radioactive waste is arranged in a capsule which also in the water is closed with an inner tightly closing cover (8). The inner cover (8) incorporates sealed holes and to the first hole in the inner cover is connected one end of a first component (18) whose other end is arranged to issue under the water surface (3a) in the basin. To the first hole is also connected one end of a second component (20) whose other end is arranged to issue at the capsule (4) lowest part. The capsule is raised so that at least the inner cover upper part is above the water surface (3a) in the radiation-screening space (14). The capsule is emptied of water via the first and second components (18, 20). To the second hole in the inner cover is connected a third component for feed of drying medium so that the capsule interior including the waste (1) is dried. To the third hole is connected a fourth component for atmospheric exchange.

IPC: B25J9/18
Filed: 1993-11-16
Abstract: A safety reset device for use together with personal safety protection device comprises two reset channels (1, 2) and a reset switch (3) common to the reset channels. Each reset channel comprises in series a reset circuit (11, 21) generating a reset signal when the reset switch (3) has been closed and opened. An input circuit (12; 22) with an input (A; B) from a personal safety protection device forwards the reset signal to a starting circuit (13; 23) if the input (A; B) is closed. The starting circuit (13; 23) operates an output relay (14; 24) if the output relay (24; 14) in the other reset channel has been released or has been closed maximally a predetermined time. The starting circuit (13; 23) further activates a holding circuit (15; 25) holding the output relay operated as long as the input (A; B) is closed. Both reset channels are completely made up of electronic components which are substantially electronically mirror-inverted, such that, when one component closes to one pole of the supply voltage in one reset channel, the corresponding component in the other reset channel closes to the other pole of the supply voltage. In this manner, an interference-insensitive electronic reset device is achieved.

Title: Mixed source signal separation method
Inventor: LINDGREN ULF
IPC: H03D1/00
Filed: 1995-05-03
Abstract: The cross correlation functions between the signals, after the summator, are calculated for the delays (K) between a first delay (K1) and a last delay (K2). A criterion function is used to determine how the linear filter in the separation structure is to be fitted in each concrete situation. The criterion function is formulated as the sum of the terms, where the summation is extended over all the possible correlation functions between the separation structure output signals, with all possible delays (k) between K1 and K2. Each term in the sum has a weighting factor, and another factor comprising an even function (f) of a specific cross correlation function at a specific delay. The number of measurable signals is two, and the function (f) is one of squaring. The filter in the separation structure is controlled by one of the algorithms LMS, Newton or regularised Newton.

Abstract: The present invention relates to an arrangement, a network and methods for identifying the relevant SDP for a question from an SCP in a telecommunication network with a large amount of subscribers and handling and administration of a large amount of subscribers by introducing a function for intelligent routing. The intelligent routing between SCP and SDP can be handled by a node standing by itself in the network or as a part-function in an already existing node, for example an SCP. When a new subscriber shall be stored in an SDP subscriber data is transferred from the service administration to a master IRF (Intelligent Routing Function). The IRF comprises a function for determining which SDP that shall store the subscriber data and the IRF thereafter transfer the subscriber data to the SDP. The IRF also stores this information. The information is also transferred to the other IRFs. When an SCP gets a call from an SSP, the SCP contacts an IRF which contacts an SDP.
